Patterns of anti-osteoporosis medication use among women at high risk of fracture: findings from the Global Longitudinal Study of Osteoporosis in Women (GLOW).

ABSTRACT:

Objective

To assess patterns of anti-osteoporosis medication (AOM) use over 3 years among women at high risk of major fracture.

Methods

The GLOW registry follows a cohort of more than 40,000 women aged ? 55 from 615 primary care practices in 10 countries. Self-administered surveys (baseline, 12, 24, and 36 months) collected data on patient characteristics, perception of fracture risk, and AOM use. FRAX scores were calculated from the baseline surveys and women classified as high risk if their FRAX 10-year probability of major fracture was ? 20%.

Results

A total of 5774 women were classified as at high risk and had complete data over 3 years. At baseline, 2271 (39%) reported receiving AOM, 739 (13%) reported prior but not current use, and 2764 (48%) said they had never used AOM. Over 3 years, 85% of baseline non-users continued as non-users and 15% initiated AOM; among baseline users, 49% continued the same medication class, 29% stopped AOM, and 12% switched. Women who stopped AOM were less likely to self-report osteoporosis (HR 0.56, 95% CI 0.42-0.75) than women who continued AOM. Compared with non-users who did not begin treatment, women initiating AOM were more likely to report a diagnosis of osteoporosis (HR 11.3, 95% CI 8.2-15.5) or osteopenia (HR 4.1, 95% CI 2.9-5.7) and be very concerned about osteoporosis (HR 1.9, 95% CI 1.3-2.8).

Conclusions

Less than 40% of women at high risk of fracture reported taking AOM. Women who stopped AOM were less likely to believe they have osteoporosis. Women who initiated treatment appeared motivated primarily by a diagnosis of osteoporosis or osteopenia and concern about the condition.

Project description:This study describes the development of a decision aid (DA), aimed at supporting patients in their decision whether to start anti-osteoporosis medication. People with recent fractures or osteoporosis and health professionals were supportive of the DA initiative. An experimental study been started to assess (cost-)effectiveness of the DA.PurposeAt fracture liaison services (FLS), patients with a recent fracture ánd osteoporosis or a prevalent vertebral fracture are advised to start anti-osteoporosis medication (AOM). This study describes the development of a decision aid (DA) to support patients and healthcare providers (HCPs) in their decision about whether to start AOM.MethodsThe DA was developed according to International Patient Decision Aid Standards (IPDAS). A systematic procedure was chosen including scope, design, prototype development, and alpha testing. A previously developed DA for women with osteoporosis was used as a basis. Furthermore, input from literature searches, the Dutch guideline on management of osteoporosis, and from people with a fracture or osteoporosis was used. The updated DA was evaluated during alpha testing.ResultsThe DA facilitates the decision of patients whether to initiate AOM treatment and provides information on fractures and osteoporosis, general risk factors that increase the likelihood of a subsequent fracture, the role of lifestyle, personalized risk considerations of a subsequent fracture with and without AOM treatment, and AOM options and their characteristics in an option grid. Alpha testing with 15 patients revealed that patient preferences and needs were adequately presented, and several suggestions for improvement (e.g. adding more specific information, simplifying terminology, improving icon use) were accounted for. Participants from the alpha testing recommended use of the DA during outpatient visits.ConclusionProfessionals and persons with osteoporosis were supportive of the proposed DA and its usability. The DA could help in a shared decision-making process between patients and HCPs.

Project description:UnlabelledLong-term persistence with anti-osteoporosis drugs and determinants for discontinuation among fracture patients were examined. Persistence was 75.0 and 45.3 % after 1 and 5 years, respectively. Those aged ≥80 years were at increased risk of early discontinuation. Within 1 year after discontinuation, 24.3 % restarted therapy, yet 47.0 % persisted for 1 year.IntroductionThe risk of osteoporotic fracture can effectively be reduced with use of anti-osteoporosis drugs. However, little is known about persistence with these drugs after fracture where subsequent fracture risk is high. The aims were to determine long-term persistence with anti-osteoporosis drugs among fracture patients, including its determinants, and to describe restart and subsequent persistence.MethodsA cohort study was conducted within the Dutch PHARMO Database Network. Patients aged ≥50 years (n = 961) who received anti-osteoporosis drugs within 1 year after fracture, but not in the preceding year, were included (2002-2011). Persistence (defined as the proportion on treatment) and the proportion restarting after discontinuation were estimated using Kaplan-Meier analyses. Time-dependent Cox regression was used to identify determinants of non-persistence including age, sex, initial dosage regime, fracture type, comorbidities, and drug use.ResultsPersistence with anti-osteoporosis drugs was 75.0 % (95 % confidence interval (CI) 72.0-77.7) and 45.3 % (95 % CI 40.4-50.0) after 1 and 5 years, respectively. A significant determinant of non-persistence was age ≥80 years (reference 50-59 years: adjusted hazard ratio [adj. HR] 1.65; 95 % CI 1.15-2.38). This effect was not constant over time (≤360 days following initiation: adj. HR 2.07; 95 % CI 1.27-3.37; >360 days: adj. HR 1.08; 95 % CI 0.62-1.88). Within 1 year after discontinuation, 24.3 % (95 % CI 20.1-29.2) restarted therapy, yet 47.0 % persisted for 1 year.ConclusionsThis study identified suboptimal persistence with anti-osteoporosis drugs among fracture patients. Major target groups for measures aimed to improve persistence may be those aged >80 years and those restarting therapy.
